src/sys/arch/i386/isa: npx.c
Log Message:
Since we always run with CR0.NE set (internal fpu using vector 0x10)
npxintr() is only generated when a process executes an FP instruction
and the TS set interrupt takes precedence - so we know the current lwp
owns the fp registers.
It is also then impossible to get a splurious error while saving
the registers.
Ths lets the npxintr() code be simplified somewhat.
XXX: I'm not at all sure it really DTRT if the process actually wished
to fixup anything in the signal handler (or even if the signal is masked).
